FLASH-TESTER.

SPECIFICATION forming part of Letters Patent No. 788,250, dated April25, 1905.

Application filed January l1, 1905. Serial No. 240,584.

To 1r/ZZ whom t muy concern,.-

Be it known that I, FERNAND A. COURTOIS, a citizen of France, and aresident of Newark, in the county of Essex and State of New Jersey, haveinvented a new and Improved Flash- Tester, of which the following isafull, clear, and exact description.

This invention relates to improvements in devices for determining ortesting the flashing-point of inliammable liquids, suoli as oils, anobject being to provide a device of' this character that will be simplein construction, easily kept clean, and so arranged that theigniting-iiame will pass over the surface of the oil in a uniform andpractically horizontal direction.

Other objects of the invention will appear in the general description.

I will describe a flash-tester embodying my invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a partothis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a sectional elevation of a lashtester embodying myinvention. Fig. 2 is a plan thereof. Fig. 3 is a perspective view of thetest-cup, and Fig. 4 shows a handle that may be employed for removingthe cup from the heating apparatus.

Referring to the drawings, 1 designates a ring-like support mounted onlegs 2, on the lower ends of which are outwardly-extended portions 3,receiving leveling-screws 4. Removably placed on the ring 1 is a `Hue 5,which receives the iiame from a heating device, such as a Bunsen burner6, supported on one of the legs 2. Removably placed in the iiue 5 is atest-cup 7, having a trough 9 at its upper portion for receiving oilthat may be passed over the top of the cup by expansion due to heat. Thecup when in position is raised slightly above the flue 5, or, in otherWords, is supported by upwardly-extended lugs 1() on the upper end ofsaid lue, the spaces be- Y tween the lugs forming ports to provide aproper draft for the heating-name.

An annular ring l1 on the outer wall of the trough9 is provided with arecess 11, the op- 5o posite Walls of which are dovetailed to engagewith the correspondingly-shaped head 12 on a handle 13, designed to beemployed for litting the cup out of the iue 5 when it contains hot oil.A gas-burner tip 14 is adjustably ar- 5 5 ranged over the upper end ofthe cup. This burner-tip is supported in a block 15 and held as adjustedby means of a thumb-nut 16, the said block 15 being adjustablevertically on a rod 17, attached to a block 18, movable on 6o one of thelegs 2 and held in position by a thumb nut 19. A thermometer20 has itslower end extended into the cup 7 when the apparatus is in use, thisthermometer being suspended from an arm 21, adjustable in a block 22,the said block 22 being adjustable on a rod 23, extended upward from anarm 24, clamped to one of the legs 2 by means of a thumb-screw 25. p

In the operation the flue 5 is to be placed 7o on the supporting-ring 1,which is to be properly leveled by means of the screws 4. The cupcontaining the oil, which reaches to within Y a short distance of theupper edge, is then to be placed in the Hue and the bulb of thethermometer placed into the oil. The Bunsen burner is to be adjusted upor down to regulate the thermometer, as required, and then theburner-tip 14 is to be adjusted to extend slightly over the edge of thetest-cup. -The 8o ilame from the tip 14, as before mentioned, will passin a substantially horizontal plane over the surface of the oil, andwhen the oil flashes its Hash-point will be indicated by the mercury inthe thermometer.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A flash-tester comprising a support, a heater`arranged underneath the support, a flue on the support, a test-cupremovably placed in the flue and having atrough around its upperportion, a burner-tip for extending' over the test-cup, andathermometer-support.

2. In a flash-tester, a support,.means for leveling the support,aheating device arranged 9 5 underneath the support, a iiue on thesupport,

a test-cup removably placed in the Hue and having a trough around itsupper portion, a gas tip or jet adjustable over the test-cup, and meansfor suspending' a thermometer in the cup.

3. An oil-testing device comprising a flue,

a heater arranged underneath the flue, atestcup removably placed in theflue and having a trough surrounding its upper portion, and

means for suspending a thermometer in the IO cup.

In testimony whereof I h ave signed my name to this specification in thepresence of two subscribing Witnesses.
